This results in the need for high precision tolerances when welding the two cooling flat tubes, a complicated welding process and high cost for the radiator
And it is impossible to control whether the power module is too tight or too loose when inserted, resulting in the power module being squeezed or the contact between the power module and the heat dissipation flat tube is not tight, and the heat dissipation efficiency is low

The invention discloses a radiator for a power module and a vehicle with the same. The radiator for a power module includes: a plurality of flat tubes for cooling, and the flat tubes for cooling are arranged at intervals along the front and rear direction, so that The power device of the power module is clamped between two adjacent heat-dissipating flat tubes, each of the heat-dissipating flat tubes is provided with a front water connection on the front surface and a rear water connection on the rear surface; Among the heat dissipation flat tubes, the rear water passage interface of the front heat dissipation flat pipe is pluggably connected to the front water passage interface of the rear heat dissipation flat pipe. The heat sink for a power module according to the embodiment of the present invention has the advantages of good heat dissipation effect, low cost and high production efficiency.
Description
technical field [0001] The present invention relates to the technical field of radiators, in particular, to a radiator for a power module and a vehicle having the radiator for a power module. Background technique [0002] In the related art, the radiating flat tubes of the radiator are connected by welding, and the process is complicated and the cost is high. Due to the high temperature of soldering, the power module must be installed between two flat cooling tubes after the radiator is fabricated. As a result, high precision tolerance is required when welding and connecting two flat heat dissipation tubes, the welding process is complicated, and the cost of the heat sink is high. In addition, it is impossible to control whether the power module is inserted too tightly or too loosely, resulting in the power module being squeezed or the contact between the power module and the heat dissipation flat tube is not close, and the heat dissipation efficiency is low.
